BACKGROUND OF THE INVENTION

A. Field of the Invention

This invention is related to a method an a machine for the production ofglassware articles and more specifically to a method and a machine, asan individual forming section including single or multiple cavities,which can be grouped to constitute a glassware forming machine of thetype including multiple individual forming sections, normally includingfrom six to eight individual forming sections, for the production ofglass bottles, jars, tumblers and other glassware articles by theblow-and-blow, press-and-blow, press-and-blow paste mold or direct-pressprocesses.

B. Description of the Related Art

Glassware articles such as narrow neck glass bottles are normallyproduced in glassware forming machines of the type which may includemultiple similar forming sections, by the blow-and-blow process, whilewide neck glass jars, tumblers and other glassware articles are producedin the so named “E” and “F” Series forming machines by thepress-and-blow process, in both, the so named hot molds and paste mold.

Glass bottles known as narrow neck glass containers, can also beproduced by the well-known press-and-blow process, in the abovementioned E and F machines.

Nowadays the production velocity or forming cycles of the machinesincluding multiple-sections and E and F machines, have reached to anoptimum status and the maximum number of glassware articles has beenachieved by providing multiple cavities (usually two to four) in eachindividual forming section of the machine.

Looking for an increasing in the number of glassware articles performing cycle on each section of the machine, attempts have been made tointroduce additional forming stations in each section, for example anadditional article forming apparatus (blow mold, blow head) which couldcarry out a forming task (receiving a just formed parison from a singleparison forming apparatus and beginning the forming blown), whileanother similar equipment is carrying out a following forming task onthe forming cycle (opening the blow mold for transferring a just formedarticle to a cooling dead plate and being prepared to receive anotherfollowing parison from the parison forming apparatus).

Representative of such forming machines, are the so named “one-twostation machines”, disclosed in U.S. Pat. No. 4,094,656; 4,137,061 and4,162,911 of Mallory, including a single stationary parison formingstation and two article finishing stations, one finishing station ateach side of the parison forming station in the same line known as the“cold-side” of the machine, eliminating the so named hot-side, and inU.S. Pat. Nos. 4,244,756 and 4,293,327 of Northup, disclosing a singleparison forming station placed in the hot-side of the machine, and twoarticle finishing stations, mounted one above the other on a lifting andlowering mechanism, alternatively rising and lowering each formingstation for forming the articles.

However, by increasing the number of forming stations, the number offorming molds and surrounding equipment (either for single or multiplecavities) are consequently increased, increasing in turn the operationcost of the machine.

Other attempts to increase the velocity of production and the quality ofthe glassware articles in the multiple-section machines and E and Fmachines, has been focused on providing three consecutive formingstations, comprising a first parison forming station, an intermediatestation for re-heating and/or stretching of the parison, and a thirdstation for finishing the glassware article.

Representative of these “three station” forming machines are the U.S.Pat. Nos. 3,914,120; 4.009,016; 4,010,021 of Foster; U.S. Pat. No.4,255,177 of Fenton; U.S. Pat. No. 4,255,178 of Braithwite; U.S. Pat.No. 4,255,179 of Foster; U.S. Pat. No. 4,276,076 of Fenton; U.S. Pat.No. 4,325,725 of Fujimoto and U.S. Pat. No. 4,507,136 of Northup.

The differences between each of these three step forming processesdisclosed by the above U.S. patents, can be firstly determined by theparison forming orientation in an upright orientation, as disclosed inU.S. Pat. Nos. 3,914,120; 4,009,016; 4,010,021, all of them of Foster,and U.S. Pat. No. 4,255,178 of Braithwait, and in an invertedorientation, as disclosed in U.S. Pat. No. 4,555,177 of Fenton, U.S.Pat. No. 4,255,179 of Foster, U.S. Pat. No. 4,325,725 of Fujimoto, andU.S. Pat. No. 4,507,136 of Northrup.

Further differences between the above disclosed three step formingprocesses, are determined by the apparatuses to transfer the parison andfinished article through the parison forming step, the intermediate stepand the finishing and take out steps.

For example, U.S. Pat. Nos. 3,914,120; 4,009,016; 4,010,021, and4,255,178 disclose a linear transference of the parison in an uprightposition from the parison forming station, to the intermediate station,then a linearly transference of the parison from the intermediatestation to a blow molding station, and finally, a linearly transferenceof the finished article, to a cooling dead plate.

Unlikely to the above disclosed glassware forming machines andapparatuses, U.S. Pat. Nos. 2,555,177; 4,255,179; 4,325,725, and4,507,136, disclose a first transference step including inverting of theparison from an inverted position at the parison forming station, to anupright position at the intermediate station; a second lineartransference step from the intermediate station to a final forming(blowing) station; and a third linear transference step from the finalforming station to the cooling dead plate. The second and third lineartransference steps being carried out by a generally similar transferenceapparatus.

Other differences between the apparatuses disclosed in theabove-referred patents can be found in connection with the very specificapparatuses to carry out the transference of the parison and the finalglassware article.

The main objective sought by the introduction of the intermediatestation in these glassware forming machines, has been to release thetask of a previous mechanism to be in an conditions to repeat a newforming cycle, without having to wait that a following mechanismperforms its respective task, to turn back at its original position tobegin a new forming cycle.

However, the above objectives have been difficult to be achieved becauseof the configuration of the mechanisms constituting the machine, whichhave been the same as the conventional and well-known ones.

Applicants, looking for a win-to-win machine, i.e. seeking to obtain theobjectives of increasing the velocity of the machine and a reduction ofthe forming cycle time, the efficiency of its performance and anincreasing in the quality of the articles to be produced, as well asseeking to make standard some mechanisms which perform similar tasks,and equipping them only with their specific instruments to perform theirspecific function, reducing as much as possible the cost of equipping amachine, the number of mechanisms in storage, and simplicity of mountingthe specific instruments on common mechanisms and apparatuses,applicants reached to the following concept of a new glassware formingmachine comprising a combination of some new apparatuses, and a newmethod for the production of hollow glassware articles.

In the first place, applicants visualized that an intermediate stationis conveniently necessary so that the re-heating of the glass surface ofa just formed parison be continued outside the blank mold in order toimmediately release the task of the blank mold, enabling it to carry outanother forming cycle, and permitting to carry out a stretching of theparison, all of which also results in an increase in the velocity ofproduction and in a better quality of the article.

Additionally, applicants recognized that the inverting arm including aneck ring mold, of a typical inverting mechanism, had to be in astanding position during a parison forming cycle and to wait for theopening of the blank mold, to initiate the inverting cycle, release theparison at the intermediate station and turn back at the parison formingposition, to begin another forming cycle.

To overcome the former disadvantage, applicants introduced a newinventive concept for the inverting apparatus, consisting in providingtwo diametrically opposed and stepped inverting arms, each holding atransferable and open-able neck ring mold (either single ormultiple-cavity), so that a first one of said arms, after a parison hasbeen formed at a first parison forming cycle, can firstly rotate 180°clockwise (moving the parison upwardly constricting it) orcounterclockwise (moving the parison downwardly stretching it) torelease the parison held by a first transferable and open-able neck ringmold, at the intermediate station, while the second arm with a secondtransferable and open-able neck ring mold is simultaneously placed underthe blank mold to perform a second parison forming cycle, and then thefirst arm with an empty transferable and open-able neck ring mold whichhas been turned back to said first arm, rotates additional 180°completing a 360° turn, to be placed under the blank mold for a thirdparison forming cycle, while the second arm is releasing the parisonheld by the corresponding transferable and open-able neck ring mold, atthe intermediate station. In this way, the blank mold do not have towait that the first arm release the parison at the intermediate stationand turn back, to initiate a new parison forming cycle.

New first and second transferable and open-able neck ring molds (eithersingle or multiple-cavity) are provided to be held and handled withabsolute independence by each of the arms of the inverting apparatus, bythe longitudinal transference apparatus and by the take out apparatus,have also been provided in order to improve the quality of the finalproduct by handling the parison by the neck ring at a uniformtemperature, thus avoiding that the formed parison had to be handled byother components at different temperatures which may cause checks,efforts or deformations in the parison, which result in a poor qualityof the finished articles.

The independence and transference ability of these transferable andopen-able neck ring molds of the present invention, is possible in themachine of the present invention because of the existence of theunidirectional indexing-rotary inverting apparatus including the firstand second stepped and diametrically opposed arms, which are able tohold a transferable and open-able neck ring mold, so that, while a firsttransferable and open-able neck ring mold is transferred from the firstarm at the intermediate station to the blown molding station for forminga finished article, the second arm with a second transferable andopen-able neck ring mold is placed at the parison forming station, in aparison forming cycle and once the parison is formed and able to beinverted at the intermediate station, the first arm has received backthe first transferable and open-able neck ring mold and rotated other180° completing a 360° turn, to be placed again at the parison formingstation.

Also, although a typical baffle apparatus could be included in themachine, mainly for the blow-and-blow forming process, this apparatuscan be configured in accordance with the machine of the presentinvention, by including a new oscillating apparatus named “rotolinearapparatus”, which may also be useful for operating a glass gob guidechannel, the blank mold apparatus, the final blow apparatus and anyother apparatus, for firstly rotate, then place an actuating mechanismto their respective active positions, and then retire them to an initialinactive position, which includes a new configuration of cams and camfollowers to impart reliable oscillation and lowering and liftingmovements, overcoming any backlash which could cause misalignment of thebaffle apparatus or any other apparatuses, with the followingapparatuses of the forming sequence.

A new equalizing apparatus has also been provided at the baffleapparatus and at the final blow apparatus, for multiple-cavity, formounting bottom blank mold heads and uniformly place them on the blankmolds or the blow molds, effectively adjusting whatever misarrange whichmay exist both, in the baffle or blow heads, or in the blank mold orblow molds.

In this way, this new glassware forming machine overcomes a number ofdifficulties of the known glassware forming machines, affording a win inthe forming cycle time, which is estimated at a 32.6%, and allows anincrease in the production and an improvement in the quality of thehollow glassware articles, as will be specifically disclosed in thefollowing detailed description of the invention.

-   -   It is suitable for the production of hollow glassware articles,        such as bottles, jars, tumblers and other glassware articles, by        the blow-and-blow or press-and-blow, press-and-blow paste mold        and direct press processes in a glassware forming machine        including multiple machine sections and multiple cavities.    -   A single machine section can be quickly interchanged at a        multiple-section machine, by another ready-for-operation one,        without retiring said multiple-section machine from the working        area, for maintenance, repairing and/or actualizing.    -   The transferable and open-able neck ring molds are placed at a        constant “zero-line” height for the different height of articles        to be produced, so that height adjustments are unnecessary.    -   The unidirectional inverting apparatus are placed at a constant        “zero-line” height for the different height of articles to be        produced and/or processes, so that height adjustments are        unnecessary.    -   The pressing plunger apparatus is placed at a constant        “zero-line” height for the different height of articles to be        produced and/or processes, so that height adjustments are        unnecessary.    -   The pressing plunger apparatus is placed at a constant        “zero-line” height for the different height of articles to be        produced, requiring only a rapid change of the pressing plunger        or neck ring plunger, so that height adjustments are        unnecessary.    -   The variable compensator of the pressing plunger apparatus,        allows to change the height of the parison    -   The servo-controlled bi-directional curvilinear transference        apparatus is placed at a constant “zero-line” height for the        different height of articles to be produced, so that height        adjustments are unnecessary.    -   The blow head apparatus is placed at a constant “zero-line”        height, for the different height of articles to be produced, so        that height adjustments are unnecessary.    -   The bi-directional curvilinear translation take out apparatus is        placed at a constant “zero-line” height, for the different        height of articles to be produced, so that height adjustments        are unnecessary.    -   The neck ring holding arms of servo-controlled unidirectional        inverting apparatus, are mounted in a reduced inversion radius        which allows a reduction of inertial forces for the inversion        servo-controlled path of the parison.    -   The oscillating mechanism is the same for guide-funnel        apparatus, the baffle apparatus and the blow head apparatus, but        arranged in a left or right arrangement only for the        guide-funnel apparatus.    -   The opening and closing mechanism, is the same for the blank        mold apparatus and the blow mold apparatus.    -   The driving mechanism is the same for the servo-controlled        unidirectional inverting apparatus, the servo-controlled        bi-directional curvilinear transference apparatus, and the        servo-controlled bi-directional curvilinear take out apparatus,        but arranged in a left or right arrangement only for the        servo-controlled bi-directional curvilinear transference        apparatus.    -   The equalizing mechanism is the same for the baffle apparatus        and the blow head apparatus.    -   The machine is able to change from a blow-and-blow process to a        press-and-blow process or direct press, and vice versa, changing        only the mold tooling, without changing any mechanism, kits or        position adjustments

It is also a main objective of the present invention, to provide a newmethod for the production of hollow glassware articles, which allows anincreasing in the velocity of production and a reduction of the formingcycle time of the machine, and an improvement in the quality of theglassware articles produced.

It is another main objective of the present invention, to provide a newmethod for the production of hollow glassware articles, in which a firstparison, held by a first transferable and open-able neck ring moldmounted on a first arm of an inverting apparatus, is inverted, by anindexed rotation at 180°, clockwise or counterclockwise, from aninverted orientation to an upright orientation at an intermediatestation, while a second transferable and open-able neck ring moldmounted on a second arm of the inverting apparatus is simultaneouslyplaced at the parison forming station, to carry out a parison formingcycle.

It is jet another main objective of the present invention, to provide anew method for the production of hollow glassware articles, in which thefirst formed parison held by the first transferable and open-able neckring mold is transferred, through a semicircular path, from theintermediate station, to a blow molding station, in which the firstparison is released into a blow mold, turning back the firsttransferable and open-able neck ring mold empty to the first arm of theinverting apparatus, at the intermediate station to be placed again atthe parison forming station, by rotating the first arm additional 180°,completing a 360° turn, while the second arm reaches to the intermediatestation to carry out a transferring cycle.

for a press-and-blow process, in an inactive position, this parisonforming apparatus, is in a retracted position maintaining the pressingplunger 209 in a position allowing an inverting path of theunidirectional rotary inverting apparatus UIA and, by the effect of theoperating fluid fed to the lower chamber 167 under the first piston 166,simultaneously releasing the fluid from the upper chamber 168 of thefirst piston rod 170, from the upper chamber 184′ of the second pistonrod 188, and from the chamber 202 of the third pressing piston 201, andtherefore the first internal spring 213 is extended, pulling thevariable adapting segment 222, and the spring SP is also expanded, inorder to place the pressing plunger 209 at a charging position;

then, once the glass gob has been fed into the blank mold BM and thebaffle apparatus BA is placed at the top of the blank mold BM, operatingfluid is fed to the lower chamber 173′ under the second piston 184,placing it at a fully extended position and automatically connecting thepassage 182 of the second end cap rod bushing 181 with the perforations189 of the hollow piston rod 188 and of internal concentric grooved tube190 for feeding operating fluid to the third final pressing piston 201,when decided, so that the pressing plunger 209 is placed at its parisonforming position; and finally, once the parison P has been finished, thefirst, second and third pistons 165, 184 and 201 are simultaneouslyretracted to its initial position for a new parison forming cycle;

By using a three-positions directional valve (not illustrated), saidcentral passage 165′ may provide both a positive or negative pressure,so that, for a blow-and-blow process, the short neck ring formingplunger 209′ at a charging position, may firstly provide a vacuumthrough the central passage 165′ and diagonal passages DP, in order thatthe glass gob completely and rapidly fills the transferable andopen-able neck ring mold 1, in addition to the settle blow provided bythe baffle head 103 of the baffle apparatus BA, and then, when thepiston 201 is retracted, the three-positions directional valve changesto positive pressure providing a counter-blow to form the parison P, andin a third position, said three-positions directional valve is underneutral inactive position.

For a convenience, an horizontal elongated nozzle NZ (shown at FIG. 6A),mounted on the top support 161′ of the first cylinder 160, provides ahorizontal compressed air curtain in order to avoid that contaminantdust particles, glass chips or grease fall down to the pressing plunger209 or short neck ring forming plunger 209′.
